Method for using encoded spreading codes to achieve high bit densities in a direct-sequence spread spectrum communication system |
摘要 |
A method for achieving high bit densities in a direct-sequence spread spectrum communication system by using encoded spreading codes. An encoded pseudo-noise code is first created. This encoded pseudo-noise code is then used to spread an information signal by modulating the information signal with the encoded pseudo-noise code. The same encoded pseudo-noise code is also used to demodulate the signal. The encoded pseudo-noise code is created by inverting one bit of a pseudo-noise code where the inverted bit corresponds to the value of the information signal.
